For a limited time, every VeloMini+ comes with a TrackR Bravo built in. Using bluetooth technology, you can keep track of your bike's last known location. TrackR also comes with a great feature called Crowd Locate. In case your bike gets lost or stolen, it can be located by piggybacking off of other people's TrackR devices. On TrackR's website, they provide a live map of all the users on their network. This way, you have a good chance of finding your bike in case the worst should happen.
